- Revive Your Car With These 8 M ...
Anytime, for any cause, a vehicle battery may die, whether brand new or aged, regardless of how often you charge it. And once that happens, many drivers panic and don’t know what to do when a car battery dies. This is when the best dead car battery tricks come in helpful.
With Diverevolve’s 8 most effective hacks below, you might just get your car started again and return to your house (or head to a garage) safely!
Let The Car Rest For A Few Minutes
Before trying any gimmicks on a drained vehicle battery, I usually recommend waiting a few minutes and attempting to restart the motor afterward. It is the most effective yet overlooked dead vehicle battery tip.
The electrochemical process constantly occurs within vehicle batteries, powering the engine’s electrical parts. Battery failures may arise from several different, unpredictable causes, making it impossible to start your car’s engine.
After sitting idle for a short period, the batteries may resume their electrochemical activities, enabling the automobile to start.
Use A Portable Jump Starter
Jump starting an automobile using a mobile jump starter is another of the most helpful dead car battery tricks.
Having a portable jump starter on hand is a good idea since your vehicle battery might die at any moment, even if it is completely new. With the help of a mobile jump starter, you may restore a bad battery in a blink of an eye.
Just plug your batteries into the mobile jump starter to restart your flat battery cells and allow them to recharge for a while.
While personal jump starters typically range in price from $150 to $270, spending a little more on a higher-quality one is well worth it. A mobile jump starter often has a compact design, making it easy to bring along in your vehicle’s truck.
Trick The Car Computer By Pushing The Gas Pedal
The most popular method of reviving a dead automobile battery is bypassing the vehicle’s system by pushing the gas pedal.
More often than not, even when the battery is brand new, our cars experience difficulties starting. Fortunately, we can fool the car’s microprocessor with a few easy tweaks and get the motor working normally.
Simply hitting the accelerator foot before engaging your car’s motor will resolve the problem immediately. This way, you may ensure that the engine receives sufficient gasoline for starting.
Apply Petroleum Jelly On The Battery
If your vehicle battery dies in the cold, you may revive it using the same petroleum jelly we apply to our bodies. Because of the electrical conductivity found in petroleum jelly, your batteries can more effectively deliver electricity to the machine.
Using petroleum jelly on the cell terminals can prevent corrosion year-round. – The List
Keeping a vehicle battery from corroding is increasingly difficult, particularly in the wintertime, and an excessive amount of rust eventually causes a car battery to fail.
Thus, to protect your vehicle’s batteries, you should routinely apply petroleum jelly to the terminals.
Jumper Cables To Jump The Dead Battery
When their car’s battery dies, most people resort to using jumper wires and another vehicle to jump-start their autos. Indeed, this is the smartest option if your car’s battery fails entirely.
Jump-starting your car with a donor vehicle is a common practice. – Your Mechanic
However, the process is somewhat tricky and dangerous if executed wrongly; you’ll need to know the proper procedure, which we already mentioned in our “Battery facts” article.
Whack The Starter With A Hammer
Don’t know how to start a car with a low battery? A starter smack might help.
A starting motor (or just “starter” for short) is vital to kick-start a car, truck, or another motorized vehicle. Indeed, a starter provides the electricity necessary to turn your engine over.
Your auto starter also relies on electricity from your batteries as well. In other words, your engine won’t crank until the starting motor receives enough electricity from the batteries.
Thus, when your car’s battery dies, your starter won’t be able to provide the vehicle with enough energy to work.
Sometimes, despite the battery providing sufficient electricity, the starting motor will not turn over your engine. The most noticeable symptoms of a failed starter unit are the grinding sounds and the starter cranking.
If your vehicle’s starter stops working, you may get it going again by striking it using a wrench or sledgehammer. Where to hit starter with hammer? Your vehicle’s starter often sits under the hood, on the driver’s front.
Rubbing The Battery Terminals
Terminals on your car batteries are the metal connectors that allow you to hook up accessories like a charger or an adapter to the batteries themselves. If your batteries are not correctly connected, you may get it to energize the motor by massaging and pressing the terminals.
A dead automobile battery often shows signs of rust, and oxidation may even spread within the terminals.
Hitting your battery terminals using a hammer or other metal component might knock off some rust and allow the batteries to deliver electricity to the motor and other electrical components as usual.
Note: A powerful smack on the battery terminals might destroy the cell, so avoid hitting it too hard.
Oxidation on the battery system may cause many troubles, including automobile electrical failures and reduced battery capacity.
A simple yet efficient tip for reviving your depleted automobile batteries is to use carbonated soft drinks to remove rust.
Looking for rusting spots on your vehicle battery is a breeze. A greenish or white film on your automobile battery contacts is a sure symptom of oxidation.
Unplug the batteries, then splash a can of cola, Pepsi, or any other carbonated drink over it to remove the rust. Once you’ve let your batteries sit for a few minutes, try starting the car.
Hopefully, with our 8 best dead car battery tricks, you know how to revive your batteries and start your car! However, the techniques above can only save you for a while! We still recommend contacting a professional service for long-term solutions (and to protect your vehicle best).
